[QUOTE="jtoews110, post: 212851, member: 11727"] I've got a few rifles with good loads worked up for them, using mostly Hogdon Retumbo. Problem is, I pay between $30-$40 a pound for it in Canada and often have trouble getting it at all. So, I've ordered a keg of WC 860 & WC 868. I've got to pick it up in person, but the price is great. The rifles I am hoping to use it in are: 264 win Pre-64 Model 70 Winchester(stock 1-9" twist) 120grn Nosler BT with 70 grn Retumbo, Fed 215 GM, chrono'd @ 3265FPS. 130grn Nosler AB 68 grns Retumbo, Fed 215 GM, chrono'd @ 3300 FPS 7mmSTW Browning A-Bolt synthetic/blued(rechambered from 7mmRM 1-9.5"twist) 140grn SGK 81.0grns Retumbo Fed 215 GM 1MOA or less 150grn Nosler BT 79.0grns Retumbo or 73.5grns RL22 0.7MOA or less. I've tried 160grn Nosler AB, but have yet to find a good load, might need more twist. 30-378wby accumark 200grn SGK 100.0grns Ramshot Magnum, Fed 215GM. 180grn Nosler AB 111 grns Retumbo, Fed 215GM, Chrono's @ 3490FPS 200grn Nosler AB 104 grns Retumbo, Fed 215GM, Chrono's @ 3260FPS. Will WC860 & WC868 work in place of the Retumbo in these loads?? What can I use as a refernce point to start from with these powders, I understand that it is best to reduce 15% and work up because of more lot to lot variation than canister powders. Jason. [/QUOTE]
